IPv6 network mobility for flat ad hoc routing protocol

We apply the mobility support of IPv6 to a wireless network where flat ad hoc routing protocol is used for interconnecting mobile routers. The use of flat routing protocol removes the need for more than one level of recursive nesting to form a wireless network backbone. We introduce a redirect header for mobile IPv6, which reduces the overhead of tunnelling by half in wireless network where bandwidth is limited. Through numerical evaluations, we show that this header aids in reducing the tunnelling overhead. We also discuss the current route optimisation proposals and their applicability to our network scenarios.
